DOOR-HANGING GAGE.

SPECIFICATION forming part Of Letters Patent N0. 435,089, dated. August 26, 1890.

Application filed April 14, 1890. Serial No. 347,831. (No model.)

To all whom it may concern;

Be it known that I, CEREAL LE FRANgoIs, a citizen of the United States, residing at Worcester, in the county of lVorcester and State of Massachusetts, have invented certain new and useful Improvements in Door-Hanging Gages, of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the saine.

The object of my present invention is to provide a gage especially designed for facilitating the hanging of doors or fitting butts or hinges to doors and jambs, said gage being provided with marking-points and means of adjustment arranged in .such manner that the proper markings for laying off the Width of the hinge-recess on both the door and the j amb are simultaneously attained by a single adj ustment of the instrument; also, to afford, in connection with the gage for the width of hinge-recesses, a marker for the thickness of the hinge-plate that can be conveniently used on the edge of the jamb without interference with the casings or finish-moldings. These objects I attain by the gage-instrumentherein shown and described. The particular subj ectmatter claimed is hereinafter definitely specified.

In the drawings, Figure 1 is a side view of my improved door-hanging gage. Fig. 2 is a bottom view of the same. Fig. 3 is an end view. Fig. 4: is a transverse section at line 00 00. Fig. 5 is a sectional diagram showing a door and jamb to illustrate the use of my gage.

In referring to parts, A denotes a bar of suitable form, furnished at one end with a head A or laterally-extended flanges, and provided on the under side thereof with a centrally-disposed undercut or dovetailed guideway a. At a central position, or at some distanc'e from the head A, a marking-point B is rigidly fixed in and projects from the under side of the bar, as illustrated.

0 denotes a sliding head mounted and adjustable upon the bar and provided with a slotted tongue 0', that extends along the bar and has its end supported in the undercut guideway a, so that it will move along the guide accordingly as the head 0 is adjusted along the central part of the bar. Said tongue 0 carries near its end a marking-point F, rig idly fixed therein, as shown. The slot bin the tongue accommodates the marking-point B and permits longitudinal movement of the tongue without interfering with said marking-point. The arrangement of the markingpoint B relatively to the face D of the gage head 0 and of the marking-point F relatively to the end face E of the head A is such that the distance from the point F to the face E will correspond with the distance from the point B to the face D plus the excess of space required as clearance for the angle of the door from the offset or shoulder of the rabbet on the door-jamb, and by reason of the adjustment of the gage-head moving the face D to or from the point B and tongue 0 simultaneously as a part of the head, carrying the point F to or from the end face E with the same extent of movement, this relation of the respective Inarking-points to the respective gage-surfaces is maintained throughout any and all adjustments of the gage. A thumbscrew G or other suitable clamping device is provided for retaining the sliding head 0 at position of adjustment.

On one side of the head 0 and projecting therefrom transversely t0 the direction of the bar I arrange an adjustable stud H, carrying a marking-point I, that gages from the side face 0 of the head 0. A thumb-screw J is provided, whereby said stud is retained at position of adjustment, as required.

The manner of using my improved doorhanging gage for laying out the position of butts or hinges on doors and door jamlbs is as follows: The gage is first adjusted so that the distance from the point B to the face D on the gage-head C will correspond with the de sired distance at which the edge of the butt R is to be located from the angle D of thedoor D (See Fig. 5.) The line B for the position of the edge of the butt can then be scribed on the door by placing the face D of the gagehead against the angle D and marking the line at B with the point B. Then with the same adjustment of the gage the line F for the position of the edge of the butt R on the jamb F can be scribed by placing the end face E of the bar'head A against the shoulder or oifset E of the rabbet and marking said line F 011 the standing janib by moving the gage along the rabbet, the part of the tool with the head 0 projecting to the front of the jamb, so that it does not interfere with the perfect working of the rabbet-gage, thus quickly and surely laying off the recess for the hinge or butt on both the door and jamb, so that they will properly correspond and at the same time afford the requisite amount of clearance in the j amb-offset, at t, to give space for the painting and varnishing without causing the door to bind or scrape the adjacent'surfaces when opened and closed. In like manner for any thickness of door or lap of the butt-plate the single adjustment of the gage-head 0 gives both the dimension for the door by the point B and face D'and the dimension of the jamb by the point F and face E, thus affording a Very convenient and useful instrument whereby the labor of hanging doors is greatly facilitated and reduced, while at the same time greater accuracy and perfection are attained in executing the Work.

The line at I for the depth of recess corresponding to the thickness of the butt-plates can be conveniently marked off by means of the side-gage point I, its carrying-stud H being previously adjusted so that the point I will stand at a distance from the edge 0 of the head 0 corresponding to the distance which the butt-plates are to be sunk into the jamb and the door. This side gage I, when constructed as shown and described, is disposed and arranged in such manner that the marking on the narrow fillet at the front of the jamb can be conveniently effected without the gage interfering with the finishing-molding P or other portion of the standing wood-work.

At the rear end of the bar A there is formed a groove a in which is fitted a slide K, preferably worked by a thumb-screw L, for carrying the marking-point m, that serves, in con nection with the face it on the head 0, for general gage purposes. This slide K and marking-point m maybe omitted, if in any instance preferred. r

I claim as my invention herein, to be secured byLetters Patent- 1. The door-hanging gage composed of the bar A, having the central fixed marking-point B, and the sliding head provided with the tongue 0', carrying the marking-point F near the end thereof, with the adjustable stud H, fitted in the side of said sliding head and carrying the marking-point I, and means for securing the adjustable parts in position, substantially as and for the purpose set forth.

2. The within-described gage-instrument, composed of the bar A, having the head A, with the end face E and guideway a, the centrally-disposed marker or point B, fixed in said bar, the adjustable gage-head 0, provided OFIREALILE FRANooIs.
